This week in Tech we pondered the future of smartwatches, learned about the tech scene in Atlanta and tried out cool new toys. Here's what you need to know about the week in Tech:

1) Smart watches from Pebble - and Apple?

Speculation was rampant last weekend that Apple will roll out a smartwatch sometime in the near future. The New York Times reported on Sunday that the device would run on Apple's iOS mobile operating system and would be made of curved glass. On Monday Bloomberg News reported that Apple has assembled a team of 100 designers to work on the watch.

We asked our Twitter followers what features they would like to see in an Apple smartwatch. Popular responses included GPS capabilities, a fitness tracker and Siri integration.

Apple will have competition in the smartwatch market if it is, in fact, building a watch device. USA TODAY's Ed Baig tried out Pebble's E-Paper smartwatch for iPhone and Android and said that "while I recognize its potential, I don't think it does quite enough yet to justify a fairly steep $150 price. It needs more apps for that." The watch can display text messages and e-mail notifications, and it can control music or phone calls on your smartphone.

But Baig raises a good point about smartwatches: Many young people don't want, or need, watches. "It's equally reasonable to question how smart it is to wear a watch that largely duplicates the information you already get off the phone in your pocket or purse, no matter how much faster it is to glance at your wrist."

Here's how it works: When a user sees an item they want to purchase, they type a special hashtag. For example, American Express is offering a $25 gift card for $15 that users can snag by posting the hashtag #BuyAmexGiftCard25.

Items that will be up for grabs with the hashtag include the Kindle Fire HD and a Sony action cam. We think this promotion sounds cool, but be very careful what you Tweet or you could make an expensive mistake!

3) Astronomers unveil contest to name Pluto's moons

First we voted on Monopoly game pieces, now we can vote on moons! Astronomers announced Monday that they are opening a contest for public voting on names for two of Pluto's recently discovered moons.

It seems that the astronomers are keeping with the time-honored tradition of naming these planetary bodies after characters from Greek literature. Choices on the ballot include Vulcan, Hercules, Styx and Orpheus.

You can also submit a write-in nomination, but don't try to submit a name related to pop culture - the SETI website has strict guidelines. "Names for the moons of Pluto must come from Greek or Roman mythology and must be related to Pluto/Hades and the underworld.

4) Talking Tech: Atlanta is 'Hotlanta" for tech start-ups

When you think of the best cities for tech start-ups, San Francisco and New York probably come to mind. But here's a new city for you to think about: Atlanta.

The Southern city is working hard to attract young tech professionals with its low cost of living. USA TODAY's Jefferson Graham talked to the members of the Atlanta Tech Village about their co-work space's growing popularity. The Village sold out 85 available desks and has a waiting list of more than 100 people.

Atlanta is currently the No. 12 city for tech start-ups, but Managing Director Johnson Cook has ambitious plans to put Atlanta in the top 10. A lot of tech start-ups working within Atlanta focus on B2B. And because the region has such a high concentration of medical providers, many also look to the burgeoning health field.

But while things are hopping, venture capital doesn't flow quite as easily as it does in Silicon Valley. "This isn't a field of dreams," says Tech Village founder David Cummings. "You can't walk in with an idea written on the back of a napkin. Here you have to prove the value on day one."

5) At Toy Fair 2013, robotic dogs, makeup mirrors and more

Zoomer is the perfect dog. He responds to the sound of your voice, he wags his tail and he doesn't make a mess. But here's the catch: He isn't real.

Jennifer Jolly took a look at the new robotic dog and other high-tech gadgets at this year's Toy Fair.

A few of the coolest toys include Lego's new Mindstorms EV3, a kit for making remote-controlled toys, and Activision's Skylanders Swap Force action figures. Jolly also tried out Barbie's new Digital Makeup Mirror. The device has a fully stocked plastic makeup counter palette and a "magic" wand that lets kids apply "makeup" to their face. The best part - it's all digital, so you don't have to worry about finding your kid covered in red lipstick.
